Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets"
"ve nghe cnc snippets" » "ve nghe cong snippets", "ve nghe che snippets", "ve nghe co snippets", "van nghe cnc snippets"
"locating bug code snippets" » "locating bung code snippets", "locating bugs code snippets", "locating bug core snippets"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"python using java snippets\") OR (\"ve nghe cnc snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( ve nghe cnc snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("ve nghe cnc snippets"))) OR ("locating bug code snippets"))*.
